ILLUMINATING DEVICE FOR TELE PHONE S Yllll I. Miyematm, San Francisco, Calif.

4 Application January as, 1934. Serial No. 707,798 I lGlaim. (oi.- 240 2.11)

This invention relates to improvements in telephone attachments and has particular reference to a light foremployment with a dial telephone, thereby enabling the user of the phone to see the numbers of the dial.

A further object of the invention is to produce a device which may be attached to the ordinary telephone without altering its construction.

A still further object is to produce a device which is neat in appearance and economical to manufacture.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a front plan view of a telephone having my invention applied thereto and showing a portion of the standard broken away,

Fig. 2 is a similar view of a French type phone,

Fig.3 is an enlarged side elevation of my invention as viewed when secured to the dial, .7

Fig. 4 is a view similar to Fig. 3 showing the reflector in raised position, and

.Fig. 5 is an enlarged detail view of one of the light switches.

In securing a number from a telephone employing a dial, it is essential that the operator of the phone must view the dial. Therefore, applicant has devised an illuminating means whereby the user can view the dial even though" the surroundings are entirely dark.

Referring to the drawing, particularly Fig. 1, the numeral 5 designates the customary standard of a desk type phone having positioned there- 36 in a pivoted arm 6 upon which the telephone receiver is hung when the telephone is out of use. The numeral '1 designates the base of the phone upon which is positioned a rotatable dial 8. The construction thus far described is commonly found in all phones and forms no part of my invention.

My invention consists in mounting upon the base 7 a support 9 which carries an insulating support 11, which extends over the dial 8 and has mounted thereon and insulated therefrom,

a plate 12 upon which is secured a socket 133.,

Into this, socket the bulb 14 is screwed. A reflector 16 is pivoted as at 1'1 to a bracket 18 and is adapted to have its free edge engaged by a clip 20. It will be noted that the bracket 18 is insulated from the plate 12 and the support 9. A wire 19 is connected to the support 9 and to a contact 21 and is mounted upon the receiver hook support 22 and insulated therefrom. This contact 21 has an end 23 which overlies the receiver hook 6. A single contact 24 overlies the contact 21 and is insulated therefrom. This contact also has an arm 26 which overlies the arm 23 and is electrically connected by a wire 60 27 to one side of a battery 28. The opposite side of the battery as is connected by a wire 29 a a center contact of the bulb 14. In Fig. 2 I have merely illustrated the manner in which the receiver actuates the switch within the phone.

This switch in Fig. 2 is similar in function to theswitchofFig.5. w

The operation of my light is as follows:-

When the device is attached to a telephone PATENT OFFI cs and the receiver hook is raised through thetaking off of the receiver, then the upward movement of the hook will cause the arm 23 to engage the arm 26 thus completinga circuit between the wires 19 and 27. Therefore, current will flow from the battery 28, wire 29 to the center contact of the bulb 14, thence through the fllament oi the bulb to the socket 13, thence to the plate 12 and clip 20, through the reflector 18 and bracket 18 to wire 19 and back to the opposite side of the battery, through the. 1 receiver actuated switch. The result is that the raising of the receiver illuminates the lamp beneath the reflector throwing the rays of illumination down- 7 upon the numbers beneath the dial 8. After I connection has been established and the userdoes not wish to have light any longer, the circuit may be broken while the conversation is in progress, by raising the reflector 16 upon its pivot 17 so as to break the circuit between the reflector and clip 20.

It will thus be seen that I have produced a light which will be illuminated immediately upon lifting the receiver from the hook and which may be extinguished by the replacement of the receiver or swinging of the reflector for the bulb, which reflector is in the electrical circuit.

Having thus described my invention,- I claim:- In combination with a telephone having a rotatable dial, a support connected to said phone adjacent said dial, an insulated plate carried by said support, a clip formed on said plate, a

bulb mounted on said plate, a reflector pivotally mounted'above said bulb and capable of being engaged by said clip, said reflector being in- "cluded in the electrical circuit for said bulb when said reflector is engaged. by said clip and to break said circuit when said reflector is pivoted out of engagement with said clip, and a remotely positioned switch actuated by the receiver of said telephone included in the electrical circuit of said bulb.
